pyln

a (WIP) Python 3D line art engine

This is a complete Python port of fogleman/ln (with some help from ln.py) using NumPy, Numba, and Pillow.

Constructive Solid Geometry (CSG) is quite intuitive:

import pyln

sphere = pyln.Sphere()
cube = pyln.Cube([-0.8, -0.8, -0.8], [0.8, 0.8, 0.8])
cylinder = pyln.Cylinder(0.4, -2.0, 2.0)
shape = (
    (sphere & cube)
    - cylinder
    - cylinder.rotate_x(90)
    - cylinder.rotate_y(90)
)

Rotate and render as a GIF:
